suppose 8 out of every 20 students are absent from school less than 5 days a year. Predict how many students would be absent from school less than 5 days a year out of 40,000 students.
8/20 = x/40,000
Calculate for x.
16, 000
To predict the number of students who would be absent from school less than 5 days a year out of 40,000 students, we can use proportions.
We are given that 8 out of every 20 students are absent less than 5 days a year. This can be expressed as the ratio 8/20.
To predict the number of students out of 40,000, we need to scale up this ratio accordingly. We can set up a proportion:
(8/20) = x/40,000
To find the value of 'x', we can cross multiply and solve for 'x':
8 * 40,000 = 20 * x
320,000 = 20x
Dividing both sides by 20:
x = 320,000 / 20
x = 16,000
Therefore, out of 40,000 students, we can predict that approximately 16,000 students would be absent from school less than 5 days a year.
